This is the first instalment of an FPGA course based on the versatile FPGA unit and associated prototyping board described in the last issue. This series of articles describes how to design digital circuits and program an FPGA. In this article, which is the first instalment of the series, we discuss the basic components of digital electronics.
In the first article of this series, we described the basic components of digital electronics and put
them to use. In this second instalment, we introduce some components that are a bit more
complicated and perform a few simple calculations using digital logic.
Part 2: Memories and calculations
we’ll use the FPGA to construct a simple microcontroller system using a (free) 8052
microcontroller core. The microcontroller drives various peripheral elements of the prototyping
board, including the I2C interface. Finally, we’ll use it to build a four-channel multimeter.
Part 3: Cores & System on Chip
In this case, the megafunction is configured to accept a 50-MHz input clock and generate a 25-MHz clock. When you use the PLL, you have to allow it a bit of time to generate a stable clock. The
‘locked’ output goes to ‘1’ when the PLL output is stable.
Welcome back to the beginner friendly course we run in support of our extremely popular FPGA Development System. This month we examine the simulation capabilities of Quartus.
Simulation makes it a lot easier to design circuits and track down errors in your designs. The accompanying examples show how you can use the audio interface of the prototyping board.
Part 4: Simulation
Every embedded system uses a system bus to transport data between the various components. This also applies to systems implemented in an FPGA. However, a different sort of bus system is commonly used in FPGAs.
